Working in Merthyr Tydfil
As well as Merthyr Tydfil itself (CF47 and CF48), we survey in Aberdare, Rhondda and Ebbw Vale.
In Merthyr Tydfil, as anywhere, the age of the house decides a lot: pipe sizes, floor construction and where the soil stack runs. Fans fitted in Merthyr Tydfil bathrooms are wired by a qualified electrician, with RCD protection and an isolator outside the room. For windowless bathrooms in Merthyr Tydfil homes, continuous extract that boosts on humidity often works better than a fan tied to the light switch.
Supplies across most of Mid Glamorgan are soft. Even so, condensation is the bigger problem in any bathroom, and a properly sized extractor is what deals with it. Hardness varies street by street, so check the figure for your postcode with your water supplier.
What the job includes
- Run-on timer, humidistat or light-linked switching set up to suit how the room is used
- Making good around the fan and checking that it extracts properly at the grille
- A backdraught shutter and external grille, so cold air does not blow back in
- A fan chosen to meet the bathroom extract rate: 15 l/s intermittent or 8 l/s continuous
Decisions to make first
Wall or ceiling
A wall fan on an outside wall is the simplest. A ceiling fan over the shower takes steam away at source but needs ducting through the loft.
Replacement air
A fan needs air to replace what it removes, so leave a gap of around 10 mm under the door or fit a door grille. A sealed room starves the fan.
Rules that apply in Wales
Wales has its own Part F with similar extract rates, and its own Part P, under which new fan wiring in a bathroom is notifiable.
